Is this microphone THX-Certified? Is there a difference between a Blue Yeti and a THX-Certified Blue Yeti?

I've been looking around for this microphone and I've noticed that some of them have a "THX-certified" logo on them, and while I was looking at the picture of this microphone at apple.com I can't see that logo. So my question is; Is there a major difference between a THX-Certified Blue Yeti / "Regular" Blue Yeti?
